A funny thing happened on the way to the campaign trail. County Executive Tom Suozzi, who is running for his third term, and GOP candidate Legis. Ed Mangano, were joined by a third-party guy. Steve Hansen, who works in the Suozzi administration as general counsel for the Office of Consumer Affairs, is running on the Conservative line. Hansen will surely play spoiler to one candidate, and most likely his presence will sting Mangano.
